Note. — The description of O. Fabricius is so short and incomplete, that the species described 

 by him cannot with any certainty be identified with this, although both the form and the colour 

 correspond so well, that it seems likely that this was the species he had before him. In the 

 ' Catalogue of the Mammalia of Greenland/ by Professor J. Reinhardt (appended to Rinks's 

 description of that country), the D. tursio, Fabricius, is, however, considered as synonymous with 

 Delphinus globiceps, Cuvier, probably from the fact that Fabricius mentions the Greenlaiidic name 

 "Nesarnak," which name is given by the Greenlanders to D. globiceps. Fabricius's description 

 seems, however, entirely to contradict this opinion ; he states, for instance : " Frons rotundata, declivis, 

 s. sursum repanda, desinens rostro attenuatiore ; sic fronti anatis mollissimæ non absimilis." This, 

 however, can agree with the Greenlanders naming D. globiceps " Nesarnak,^^ as it may have arisen 

 from an accidental confusion of the two species. The figures of the skull left by Camper seem fully to 

 correspond with the present species; and as Cuvier refers to those figures, I do not doubt that the 

 species described by him is the same, although his figures of the skull difl'er in the nose being too 

 long. The figure of the animal by Schlegel differs so much, that I have not been able to quote him 

 without a ?, more especially as even his description deviates somewhat. He has, for instance, counted 

 14 dorsal vertebræ on at least two skeletons, while I found only 12 on the skeleton that I had an 

 opportunity of examining. 



It reaches quite a large size, at least 10' — 12' in length. Clarke gives {loc. cif.) the follow- 

 ing measurements of the specimen described by him, vi^hich was a female. Length 8' 4" (English), 

 circumference at the thickest part 4', length of nose 4", height of dorsal fin 8", its base 

 1' 4" long, length of fore edge of the pectoral fins, 1' 1", width of caudal fin 1' 8". The nose, 

 although limited behind by a conspicuous notch, and apparently somewhat longer, is, however, 

 more obtuse than that of the last-described species. The dorsal fin is rather high, but not very 

 much directed backwards, and is about half way between the point of the snout and the tip of 

 the caudal fin. The pectoral fins are half way between the point of the snout and the beginning 

 of the dorsal fin, and the anal opening half way between the end of the dorsal fin and the base of 

 the caudal (Clarke). The same author states the colour to be as follows, viz., upper part of the body 

 black, sides grey, or grey with a tinge of purple, and lower side white, with some darker shades. 

 Professor C. J. Sundevall has described the colour of a young specimen, sent last summer from 

 the coast of Bohuslån (Sweden) to the National Zoological Museum of the Royal Academy of 

 Stockholm as being, " belly black ; side, from anus to point of lower jaw, pure white ; but the 

 point of the lower jaw grey or blackish ; two hght (whitish, but not pure white) streaks without
